Top Plate Fifth Wheel
SAF-Holland

Top plate assemblies in fifth-wheel systems are the primary load-bearing interface between the tractor and trailer. This plate is designed to withstand substantial vertical and horizontal loads while maintaining precise alignment with mounting rails and kingpin hardware. The component is part of the fifth-wheel family (category_id 42763) and carries VMRS code 059-001-001, which covers top-plate and related hitch components. Its engineering supports high-pull applications and repeated dynamic loading encountered in highway operation, contributing to smoother disengagement, stable coupling, and consistent height relationships between trailer and tractor. With compatibility across SAF-Holland mounting patterns and standard rail configurations, it serves as a robust replacement or upgrade for aging plates, delivering predictable performance, reduced wear on locking mechanisms, and improved safety through reliable engagement across varied trailer configurations.
